Pillar 3a for U.S. Citizens
How a Swiss pillar 3a is treated for U.S. tax, the PFIC question for invested 3a accounts, and what to watch for.
A pillar 3a is excellent for your Swiss taxes. For your U.S. taxes it's more nuanced — and an invested 3a can quietly become a PFIC issue.
Cash 3a vs invested 3a
- A 3a savings account holds cash — no PFIC, though it's still a reportable foreign account.
- An invested 3a (e.g. VIAC, finpension, Frankly) holds non-U.S. funds, which are generally PFICs for a U.S. person.
The Swiss tax deduction for 3a contributions does not carry over to your U.S. return.
What to watch for
- PFIC / Form 8621 exposure on the funds inside an invested 3a.
- FBAR / Form 8938 reporting of the account itself.
- Whether the wrapper raises foreign-trust questions (a debated, fact-specific area).
If you already hold an invested 3a, listing the funds inside it is a good first step. The Tax Risk Check flags whether a review is likely worthwhile.
